Firstly, observed the values of the demographic parameters using indirect techniques and secondly, take necessary future plan of action on the basis of the findings for the nation of country.

to understand the concepts of single, double and multiple decrement life tables.

to observed eliminating effect of specific disease on expectation of life.

to estimate different parameters of vital events using indirect techniques in absence of direct information.

to understand the concept of population growth models and their graduation.

to understand the application of projection matrix for fertility and mortality.

to understand the concept of fecundability, its distribution and effect the use of contraceptives.

The fields of application include public health, reproductive health, population policy, such as fertility, mortality, migration etc.
